Brass Motor Shaft Hub - 4mm
Brass hub kits for connecting wheels to motors! All of our hubs look identical but have different sized motor shaft diameters ranging from 3mm to 7mm in 1 mm increments. Please measure your motor shaft size carefully before buying these hubs.
These are brass, rigid type couplers, which are great for small motor robotics, e.g. RC planes, boats, cars, robots. The hubs feature a motor shaft input hole on one end, and a 12mm hex and M4 screw point for fixing on the other. Most 1/10 scale RC wheels are 12mm hex. Works well with our YetiBorg Wheels. Please Note. This is for the coupler and screws only. Mounting bracket, motors & wheels are not included.
This hub is the same size used on our DiddyBorg robots and is compatible with:
